+ URLs with relative paths
+ * Modified QUrl to not normalize %HH in URLs unless strictly

+****************************************************************************
+* Platform Specific Changes *
+****************************************************************************
+
+Unix
+ * Made the iconv-based QTextCodec class (the "System" codec on
+ Unix systems that support it) stateful. So it's now possible to
+ feed incomplete multibyte sequences to the toUnicode function,
+ as well as the first character in a UTF-16 surrogate pair.
+
+X11
+ * Added a QGtkStyle to integrate with GTK+ based desktop environments.
+ * If font config is used the default font-substitutions will no longer be
+ used instead we rely on fontconfig to determine font substitutions as
+ required.

+ * [228770] Fixed a problem that caused the .ps and .pdf filename
+ extensions
+ to not update in the CUPS printer dialog when printing to file.
+ * [230372] Fixed a problem where the number of copies set on a QPrinter
+ object wasn't picked up and updated properly in a QPrintDialog.
+
+Windows
+ * Cleartype rendering was previously supported onto QImages with
+ an ARGB32 channel. For performance reasons, cleartype is now
+ only supported on opaque images using the RGB32 or
+ ARGB32_Premultipled format. Widget and pixmap rendering is
+ unchanged
+ * [175075] Antialiased font rendering quality has been greatly improved
+ by taking gamma correction into account. We should now match the native

+ * [205985] Fixed a problem with reusing a QPrinter object to print several
+ jobs with the Microsoft XPS printer driver.
+ * [196281] Fixed QPrinter::setPrintRange() to work under Windows.
+
+Windows CE
+ * Support for QLocalSocket and QLocalServer added.
+ * QtWebKit and Phonon are now supported.
+ * One can mark a widget with the attribute WA_ExpectsKeyboardInput
+ to automatically display / hide the standard input panel on focus
+ events.
+ * [223523] Reimplementations of standard library functions filled the
+ global namespace causing problems when linking statically to other third
+ party libraries using the same attempt.
+ * Support for using OpenSSL with Qt on Windows CE
+
+Mac OS X
+ * Added the macdeployqt tool that simplifies application deployment.

+ native file dialog is fixed.

+ the modal window that opened the pop-up.
+ * [210912] - Show event not sent when reshowing a window from minimized
+ state is fixed.
+ * [228017] - QMenu will now close when expanding a system menu.
+ * Added support for Qt to use Cocoa as its backend instead of Carbon. This
+ is primarily for 64-bit applications, but is also available for 32-bit
+ frameworks as well. 32-bit is still Carbon by default. Passing a 64-bit
+ architecture or -cocoa on the command-line will build Qt against Cocoa.
+ Using Cocoa requires Mac OS X 10.5 (or higher) and cannot be used with
+ the -static nor -no-frameworks option. The define QT_MAC_USE_COCOA is
+ available when Qt is built against Cocoa.
+ * Fix a bug that would prevent a window that had been maximized via
+ setMaximized() to go back to normal size when clicking on the window's
+ maximize button.
+ * Added QMacCocoaViewContainer for embedding Cocoa (NSView) controls into
+ a Qt hierarchy. This feature works for either Carbon or Cocoa, but
+ requires Mac OS X 10.5 or greater.
+ * Added QMacNativeWidget for embedding Qt widgets into non-Qt windows
+ (Carbon or Cocoa).
+ * Added MacWindowToolBarButtonHint for controlling whether or not the
+ toolbar button is shown in Qt windows.
+ * QEvents posted via QEventLoop::postEvent() are now treated as a standard
+ event loop source, like timers and normal input events. This means that
+ is should no longer be necessary to run a busy loop to sendPostedEvents()
+ when QApplication is not the main event loop (e.g. when using Qt in a
+ plugin).
+ * [239646] Shortcuts for sub-menu are now disabled when the menu item is
+ disabled.
+ * [241434] Honor the LSBackgroundOnly attribute if it exists in the
+ application's Info.plist.
+ * [239908] More robustness when encountering different types in reading
+ LSUIElement value.
+ * [234742] Add support Qt::XButton1 and Qt::XButton2.
+ * [236203] Much better support for loading multiple Qt's with different
+ namespaces.
+ * Add Qt::AA_MacPluginApplication that allows bypassing some native menu
+ bar initialization that is usually not desired when running Qt in a
+ plugin.
+ * [205297] Applications Dialogs are now marked as application modal in
+ Carbon.
+ * Tooltip base is now set correctly in the application palette.
+ * [222912] [241603] Qt applications no longer reset their palette back to
+ the system palette on every application activate. Only if the values
+ from the system are different from the last time. This should result in
+ custom palette colors/brushes being kept across application activations.
+ * [211758] Fixed a clipping problem when printing multiple pages on a Mac
+ OS X printer.
+ * [212884] Fixed a crash when printing images on Mac OS X.

+
+****************************************************************************
+* Plugins *
+****************************************************************************
+
+- QTiffPlugin
+- QSvgIconEngine
+
+****************************************************************************
+* Important Behavior Changes *
+****************************************************************************
+
+- Event filters
+
+- QFileDialog
+ On Mac, native dialogs are now used when calling show, open, or exec
+ on a QFileDialog, QColorDialog, QPrintDialog, or QFontDialog (i.e not
+ only when using the static functions)
+
+ QFileDialog/QFileSystemModel always return Qt separators ("/")
+ regardless of the platform. It can still handle native separators for
+ Windows. To convert the Qt separators to native separators use
+ QDir::toNativeSeparators().
+
+- QGraphicsTextItem
+ Tab input is send to the document by default, inserting a <tab>
+ character. You can get the old behavior of switching Tab focus by
+ setting setTabChangesFocus(true) (QGraphicsTextItem's Tab handling now
+ behaves identically to QTextEdit and QTextBrowser).
+
+- QGraphicsView
+ QGraphicsView now propagates Qt::Key_Tab and Qt::Key_Backtab to the
+ scene, which sends this to the items. Similar to how QWidget works,
+ this event is caught in QGraphicsItem::sceneEvent() and
+ QGraphicsWidget::event() to handle tab input. Tab input is also
+ proxied to embedded widgets. This allows and item or widget to handle
+ Tab keys (e.g., text input).
+
+- QLocale
+ The locale database was updated to the Unicode CLDR database
+ version 1.6.1
+
+ When the system locale is changed, the LocaleChange event will
+ be sent to all widgets that don't have a locale explicitely
+ set.
+
+- QWebPage
+ Starting with Qt 4.5, the base brush is used for the default
+ background color of the web page. Before, it was the background
+ brush.
+
+- QWidget
+ Font and palette settings assigned to QWidget directly take
+ precedence over application fonts and palettes.
+
+ Focus policies that are set on a widget are now propagated to
+ a focus proxy widget if there is one.
+
+ Windows with fixed size (that are set with QWidget::setFixedSize()
+ function or Qt::MSWindowsFixedSizeDialogHint window hint) might
+ not have a maximize button on the titlebar.
+
+ The behaviour of the window hints was changed to follow the
+ documentation. When the Qt::CustomizeWindowHint is set, the
+ window will not have a titlebar, system menu and titlebar
+ buttons unless the corresponding window hints were explicitely
+ set.
+
+ Setting Qt::WA_PaintOnScreen no longer has any effect on
+ normal widgets. The flag can still be used in conjuction with
+ reimplementing paintEngine() to return 0 so that GDI or
+ DirectX can be used, as previously documented.
